Some people have never gotten a vaccine shot….
Some numerous ones…..
Seems new studies point to having the vaccine given in one’s nose as being more direct then the current arm injection….
Of course some people think Covid vaccines’ are nonsense …..
And turned treatment and prevention into a political football….
Human’s DO like to gamble…..
Scientists are hopeful a new type of vaccine in development could give us a better shot at fighting COVID-19 — without involving any type of shot at all.
Clinical trials are underway for a type of intranasal vaccine, which is administered by spraying into the nose, not injecting into the arm. While current vaccines and boosters are very effective at preventing severe disease and death, the hope is that a nasal vaccine would be even better at preventing mild illness….
“These will induce immunity in the mucosa of the nasal pharynx – the site of initial viral replication – and may prevent infection and reduce transmission,” said Dr. William Moss, a professor of epidemiology at the Johns Hopkins Bloomberg School of Public Health.
Nasal vaccines, because of where they are administered, work to immediately strengthen antibodies in the mucus and nose. “Mucosal immunity,” Moss explained, could prevent infection before the virus is able to spread throughout the body.
“Scientists have learned that the virus first infects the nose and throat before sometimes spreading to the lungs, where severe COVID-19 can develop. But the nose and throat are difficult destinations for the SARS-CoV-2 antibodies that develop in the blood after a vaccine is injected into the arm or leg – making those hard-to-reach areas targets for better vaccines,” wrote the National Institute of Allergy and Infectious Diseases (NIAID)…..
